A guerrilla gardener’s idea of a French potager is the cultivation of concrete.  Even with a small budget, a garden in a concrete jungle can be acquired.  

Using a jackhammer, rows were created in the concrete, just wide enough to drop in some soil amendments and small plants. The result: a low-maintenanace, minimalist garden which also serves as a food and flower source. Simple genius.
